Our stay there was comfortable as three friends who were traveling to Bangkok. It was adequately clean and there were all the essential items we needed during our short stay there. The beds were comfortable and the AC were at a good temperature. If you're sensitive to traffic noises at night, I'd recommend you bring some earplugs especially if you're staying in the room that is closer to the main street.
The location was great - we could get to everywhere we needed to within 20 minutes (if the traffic was not so bad). A perk of the flat is also the sunroof porch area, which we hung out on often. It is also right next to the train that takes you directly to the airport! Super convenient.
